TeleMoMa: A Modular and Versatile Teleoperation System for Mobile Manipulation

no code implementations12 Mar 2024 Shivin Dass, Wensi Ai, Yuqian Jiang, Samik Singh, Jiaheng Hu, Ruohan Zhang, Peter Stone, Ben Abbatematteo, Roberto Martín-Martín

This problem is more severe in mobile manipulation, where collecting demonstrations is harder than in stationary manipulation due to the lack of available and easy-to-use teleoperation interfaces.

Mini-BEHAVIOR: A Procedurally Generated Benchmark for Long-horizon Decision-Making in Embodied AI

1 code implementation3 Oct 2023 Emily Jin, Jiaheng Hu, Zhuoyi Huang, Ruohan Zhang, Jiajun Wu, Li Fei-Fei, Roberto Martín-Martín

We present Mini-BEHAVIOR, a novel benchmark for embodied AI that challenges agents to use reasoning and decision-making skills to solve complex activities that resemble everyday human challenges.

Causal Policy Gradient for Whole-Body Mobile Manipulation

no code implementations4 May 2023 Jiaheng Hu, Peter Stone, Roberto Martín-Martín

Current approaches often segregate tasks into navigation without manipulation and stationary manipulation without locomotion by manually matching parts of the action space to MoMa sub-objectives (e. g. learning base actions for locomotion objectives and learning arm actions for manipulation).

GLSO: Grammar-guided Latent Space Optimization for Sample-efficient Robot Design Automation

1 code implementation23 Sep 2022 Jiaheng Hu, Julian Whiman, Howie Choset

In this work, we present Grammar-guided Latent Space Optimization (GLSO), a framework that transforms design automation into a low-dimensional continuous optimization problem by training a graph variational autoencoder (VAE) to learn a mapping between the graph-structured design space and a continuous latent space.
